HOWARD, PENNSYLVANIA.

CURRENT-MOTOR.

Application filed February 15, 1916.

To all autom t may concern? Be it known that I, Cmnnncn C. COOKE, acitizen of the United States, and a resident of Howard, in the county ofCenter and State of Pennsylvania, have invented a certain new and usefullniprovement in Curthe following is a specification. v

My invention relates generally to current motors, and more particularlyto an arrangement the main object of which isv the provision of meanswhereby to do away with the necessity of transverse dams, and thusenable the erection of the moto1 at any point within a stream withoutencroacliing upon the riparian rights of others.

ln the accomplishment of this object, it is necessary to provide anendless bucket motor of such a nature as to operate with the an opensluiceway, and particularly one capable of operation in connection witha sluiceway adapted to form part of a longitudinal dam having currentdeflecting wings extending` upstream and at an angle thereto below thenormal water level, so as to permit of the passage of ice and othermatter upon the surface of the stream as desired.

The means and mechanism by which these objects are carried out, areshown in the preferred form in the accompanyingdrawings, forming a partof this specification, and wherein- Figure 1 is a plan view illustratingthe r arrangement proposed by my invention.

Fig. 2 is a vertical longitudinal section taken therethroughsubstantially on line 2`2 of Fig. 1.

Fig. 3 is a vertical transverse section taken substantially on line 3-3of Fig. 2, and

Fig. Ll is a detail perspective view of a portion of the endless memberwith one of the buckets proposed as a part of my improvenients.

Referring now to these figures, I construct a wall spaced from and bank11 of whether the bank is high or low, the wall being in uprightposition with its upper edge well above the high water mark throughoutits length. At the upper end of the wall 10 a transverse wall 13 of theheight of the said upper wall 10 connects the lat ter with the bank 11as particularly seen in Fig. 1, and substantially from the angleSpccicatcn of Letters Patent.

parallel to theV a stream 12 irrespective of Patented leba 13, 1917.,serial ivo. 7a4-ii.

between the walls 10 and 13 an angular current deflecting wing 1d isextended outwardly into the stream 12 in an upstream direction, thiswall being of considerably less height than that o" the walls 10 and 13as will be seen by reference to the dotted lines in lF ig. 2, so as toterminate some distance below the normal level of water in the streamand thus obviate any material retardation of the flow so as to obviatestoppage of surface matter or. encroachment upon the riparian rights ofothers along the stream at a lower point.

`djacent the angle between the walls 10 and 13, or in other words,adjacent the outer end of the transverse wall 13, the latter is providedwith an opening 15 as best seen in Fig. 2, leading to the the sluiceway1G formed in connection with the longitudinal wall 10 along' the innersurface thereof, the said opening 15 in the upper end of the sluicewaybeing at a suitable point below the normal surface of water in thestream 12 to obtain the desired head, and lia-ving its lower endterminating above high water niark.

To this end, after the walls 10 and 13 are constructed, the normal baseof the stream iiiclosed by them may be dug out to a considerable extent.

Adjacent the upper and lower ends of the sluiceway 16, are mountedtransverse shafts 17 and 18 respectively having pairs of spaced sprocketwheels 19 and 20, the sprocket wheels 2O of the lower shaft 13 beingconsiderably larger than the sprocket wheels 19 of the upper shaft 17.he latter shaft may also be provided with a pulley 21 or other suitablemeans from which the power developed by the motor may be traiismitted toa suitable point of construction.

Over the sprocket wheels 19 and 20 travel spaced parallel chains 22, thelinks of which are at spaced points connected by transverse shafts 23 asshown in Figs. 3 and -1 and upon which shafts are loosely journaledextensions 24 at the inner side edges of the buckets 25, the outer sideedges of which are connected by links 2G to the chains 22, which linksare pivotally united to the parts they connect as just mentioned so asto permit the buckets, though normally held in positions outstanding atright angles to the chains, in their passage between the shafts 17 and18, to flex as they pass around tho sprocket wheels 19 and 20. Thechains 22 may be controlled by a chain tightener 22, as shown in Fig. 2.

It is to be particularly noted that each oi' the buckets 25, open at oneside so as to receive therein, the water passing into the upper end oithe sluiceway through opening 15, is provided at its opposite side witha funnel shaped extension 27, the opening 2S of which substantiallyforms a pressure nozzle through which the current expands into the spacebetween the said buckets and the next preceding bucket, and thencethroughout the entire series of buckets within the sluiceway so as toeliminate all dead water between the buckets which would otherwiserequire the pressure at the bucket adjacent the inlet opening 15 to pushthe entire series oi' buckets within the sluiceway in addition toturning the shafts 17 and 18.

It will therefore be seen that, due to the particular construction or'the buckets as shown, 1 am enabled to utilize the same to the endsdesired within an ordinary sluice way and that due to this Jfact thissluiceway may be erected in connection with a longitudinal wall so as totake full advantage of the head ci water provided by the longitudinaldam construction first above described.

1. A current motor including` a longitudinal dam consisting of a wallparallel to, and spaced from, the bank of a stream and extending abovethe normal water level thereof, a transverse wall connecting the upperend of the said longitudinal wall with the bank of the stream and havingan opening below the normal water level and adjacent the angle betweenthe walls, a wing extending angularly in an upstream direction substantially from the angle between said longitudinal and transverse walls i'orthe deflection of current into the opening of the latter wall, asluiceway formed in connection with the longitudinal wall with its upperend adjacent the opening of the transverse wall to receive currenttherefrom, and having its lower end terminating above high Copies ofthis patent may be obtained for five cents each, by addressing the watermark, and an endless impulse member operating within and mounted inconnection with said sluiceway.

2. A current motor including a longitudinal dam consisting of a wallparallel to, and spaced from, the bank of a stream and extending abovethe normal water level thereof, a transverse wall connecting the upperend of the said longitudinal wall with the bank of the stream and havingan opening below the normal water level and adjacent the angle betweenthe walls, a wing extending angularly in an upstream directionsubstantially from the angle between said longitudinal and transversewalls for the deiiection of current into the opening of the latter wall,a sluiceway formed in connection with the longitudinal wall with itsupper endadjacent. the opening of the transverse wall to receive currenttherefrom and having its lower end terminating above high water mark,the said vertical and transverse walls extending substantially above thenormal water level of the stream and the said wing end substantiallybelow the normal water level of the stream, and an endless power membermounted in connection with the said longitudinal wall and operatingwithin the said sluiceway.

3.1n a current motor of the type described, an endless power memberincludingV a plurality of buckets open at one side and having at theiropposite sides nozzles projecting away 'from the same and establishincommunication between opposite sides of the buckets. v

4. 1n a current motor of the type described, an endless flexible powermember having outstanding buckets each of which is open at one side andprovided at its opposite side with a :tunnel-shaped extension, theaperture oit which communicates with the interior of the bucket, for thepurpose described.
